In Journey to the West, the status of dragon is really not high. As a figure within the system, he is subject to strict control by heaven. If something happens, his head will be lost. However, the Dragon King of the Four Seas does not belong to this category. Not only that, after making friends with some fairies, Heaven also turned a blind eye.
Heaven has a strict attitude towards goblins. In order to exterminate the goblins, it even sent out the "Zhenwu Dangmo Tianzun", but the goblins were conquered from all directions and stopped after killing most of them. This shows that the heaven is extremely strict on this. Before Sun Wukong ascended to heaven, he could only be regarded as a fairy with some abilities. The Dragon King of the Four Seas had a very kind attitude towards him, and he kept saying "Great Immortal, Great Immortal". It is not difficult to see from this that the Dragon Kings are accustomed to this kind of thing and have encountered similar situations before, so they are not dissatisfied with Sun Wukong's rudeness.
It is not strange for the dragon clan to make friends with some goblins. For example, the old Dragon King in Bibotan not only befriended the Bull Demon King, but even his son-in-law was a Hydra. If the son-in-law hadn't been too greedy, nothing would have happened to the old Dragon King. And the Dragon King of the Four Seas handed over the most awesome goblin in Journey to the West. This goblin's identity is quite special. He can make Buddhist Arhats, Dragon King of the Four Seas, and Eight-hole Immortals all present with a single letter. Sun Wukong didn't believe it at first, but later he saw this big demon and realized it was true. It was even more powerful than Sun Wukong had heard. This demon is none other than Tathagata's uncle, the Dapeng.
Although Dapeng is a Buddhist, he is very murderous. It can be seen from his actions after occupying the Lion and Camel Kingdom. The whole city was killed to the last person, and then he was killed by the goblins. Occupied, it became a demon city. However, the Dragon King had a good relationship with Dapeng, but the Heavenly Court turned a blind eye. Dapeng even had a network of relationships all over the Heavenly Court, and had friendships with the Immortal of the Eight Holes and the Underworld, but he still chose to acquiesce. Why? Mainly it has to do with Dapeng’s backstage Tathagata.
As the strongest goblin in Journey to the West, Dapeng also has the biggest background. He is the uncle of Tathagata. Even if he does something wrong, he will not be punished. This is reflected in the story of Peacock Daming King You can see it on your body. The peacock killed people at will, and even ate the Tathagata. After the Tathagata broke the peacock's body, he wanted to kill him, but the Buddhas stopped him, saying that killing him was like killing his mother, so the peacock was taken back to Lingshan. Dapeng's situation is similar. Even if he kills tens of millions of people and massacres an entire city, he is still Tathagata's uncle, and all the Buddhas will protect him.
The reason why the Heavenly Court indulged the Dragon King in making friends with such a great demon was partly because he saw the value of Dapeng. Dapeng is like a powerful but over-expanded person. He is sinister and cruel. But as long as he is flattered and happy, he can bring more benefits to himself. It is still a good thing for Heaven. As for how many bad things they have done, they have not done it. Don't want to pay attention.
